Skodacurfutita

I think the first time just one or two of them were changed around 60000 km, so now ive changed all 4 just to be safe.

@Blue8793841 There could be also a posibilitly of faulty ones, next time i will replace them myself to avoid all the issues. :))

Updates, it seems the problem were the spark plugs, more precise the brand. First time they were bosch. This time i dont know the brand. But the car acts normal now and i have a normal fuel consumption. Thank you.

Hi all, I have some small misfires with my Skoda Octavia, year of fabrication 2017, mileage: 102000 km, engine 1.4 tsi 150hp, engine code CZDA, dsg gearbox. One month ago when i started my skoda, the check engine turned on and in gears: 1,2,3,4 between 1000-2000 rpm i had big misfires. I took it to the service (its not a skoda service, its for multiple car brands) and they replaced the spark plugs according to the diagnosis. After they replaced the spark plugs the car started to consume more gasoline with almost 3-4 liters /100km, so from 5.5. it went around 8-9 on a highway at around 100KM/H which in my opinion is a big fuel consumption, usually it was consumig 5-5.5 at 100KM/H. After 500 KM the check engine turned on again and again i have misfires, this time smaller ones between 1000-2000 rpm in gears 1,2,3,4. the consume still remained high at around 8-9. Now the car is in service already for a week now ,and i called them today and they told me that they still did not fix it because is a puzzle to find out what is wrong. What could possible cause those missfires and high fuel consumption? Thank you everyone for your opinion.
